[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a disposable diaper, and more particularly to a disposable diaper suitable for use by adult men.

[0002]

2. Description of the Related Art In the use of disposable diapers, the position of the penis relative to the diaper is not fixed in adult males, and the male penis often causes side-over as compared with adult females.

[0003] As a prior art for preventing the side leakage, there is, for example, US Patent No. 4,704,116. In the diaper disclosed in the publication, a pair of flaps symmetrical with respect to a center line bisecting the diaper to the left and right are provided on the topsheet, and the outer edge and the end edge of the flaps are joined to the topsheet, while the inner edge is By making the elastic member a stretchable free edge that is adhered under extension, when the diaper is worn, these flaps stand on the topsheet and can block the body fluid flowing in the diaper's lateral direction. It is like that.

[0004]

In the prior art, if the distance between the free edges of a pair of left and right flaps is appropriately reduced, the penis can be lightly pinched from the left and right to restrain its movement, and the penis can be restrained. It is considered that the diaper can be held at the center in the width direction. However, in such a case, there is a problem that the distance between the flaps in the vicinity of the anus is too small, and the stool cannot be received well.

[0005] Even when the flap is made of a soft nonwoven fabric, the free edge is increased in rigidity by sticking the elastic member, and the free edge becomes jagged due to the formation of gathers. Doing so has the problem of hindering the feeling of wearing.

[0006] In view of the above, the present invention relates to the above-mentioned prior art by bending a nonwoven strip extending from the front body to the crotch region from the inside to the outside of the diaper and holding the penis between the bent portions. The task is to solve the problem.

[0007]

The present invention solves the above-mentioned problems by the following means.

In this invention, a disposable diaper having a liquid-permeable core sheet between a liquid-permeable top sheet and a liquid-impermeable back sheet and having a crotch region between the front body and the back body in the longitudinal direction is provided. It is a premise.

[0009] On this assumption, a pair of flaps, which are constituted by strips made of non-woven fabric, extend in the longitudinal direction from the front body to the crotch region, and are symmetric with respect to the center line in the left-right direction of the diaper, are provided on one side. To the topsheet at the outer edge side of the diaper, fold the remaining other side toward the outer edge, overlap the edges of one side and the other side and join the topsheet, and others It is a feature of the present invention that the elastic member is attached to the side portion in the longitudinal direction thereof while extending, and the interval between the bent edges of the pair of flaps is set to a required size.

[0010]

In the diaper having such a configuration, the interval between the bent edges of the pair of left and right flaps is set to a required size,
By pinching the penis from the left and right at the bent edges, the movement can be restrained and urination can be concentrated at the widthwise center of the diaper. When the diaper is put in the worn state, the elastic member contracts to raise the flap from the topsheet, and the flap blocks urine flowing laterally on the topsheet.
Since the elastic member is located at the side edge portion of the flap turned outward, it does not touch or press the penis.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the disposable diaper according to the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a partially cutaway perspective view of a disposable diaper 1, showing a front body 2, a back body 3, and these bodies 2,
The diaper 1 including the crotch region 4 interposed between the three is in a state of being slightly curved inward in the longitudinal direction. The diaper 1 has a liquid-permeable top sheet 5, a liquid-impermeable back sheet 6, and a liquid-absorbent core 7 interposed between the front and back sheets 5, 6, and a top sheet from the front body 2 to the crotch region 4. A pair of flaps 8 symmetrical with respect to the center line CC in the left-right direction of the diaper 1 are provided on 5, and one end of a tape fastener 9 is non-peelably joined to the left and right side edges of the back body 3. The waist elastic members 11 and 12 are provided at the ends of the front and rear bodies 2 and 3 respectively.
Is attached to the recessed portion provided in the crotch region 4, and the leg elastic member 13 is attached to the recessed portion.
The flap 8 is obtained by folding a nonwoven fabric strip toward the outside of the diaper 1 along a folding curve (edge) 21 parallel to the center line C-C. Is joined to the topsheet 5 at the joining line 15A, and the other upper side edge 16 becomes a free edge, and in the longitudinal direction, a plurality of elastic members 20 extend downward. It is stuck. The edge portions 17 and 18 of the strip pieces are joined to each other at the folded portions and joined to the top sheet 5 at joining lines 17A and 18A, respectively.

FIG. 2 is an end view taken along line XX of FIG. The interval D between the folding curves 21 of the left and right flaps 8 is set to a size that can accept the penis of the wearer. The side edge 15 of the flap 8 is joined to the topsheet 5 via a welding wire 15A,
The side edge 16 covers the elastic member 20 by bending the edge. The liquid-absorbent core 7 is particularly thick between the left and right welding lines 15A, so that the absorption rate and retention amount of urine intensively excreted here are higher than the outer part. . However, a large amount of the superabsorbent polymer may be provided here to increase the amount of urine absorbed and retained without locally increasing the thickness of the liquid absorbent core 7.

FIG. 3 is a perspective view of a diaper 1 having a mode different from that of FIG. The diaper 1 has a relatively long second flap 25 extending between the front body 2 and the back body 3 outside each of the first flaps 8. The second flap 25 is also a non-woven strip, the outer edge 26 of which and the edge 2
7 and 28 are joined to the topsheet 5 at joining lines 26A, 27A and 28A, respectively, and the inner edge 29 is a free edge.
, An elastic member 30 is adhered in a longitudinal direction thereof while being extended.

When the diaper 1 constructed as described above is worn while being bent inward, the elastic member 20 is provided in the flap 8 and the elastic member 3 is provided in the flap 25.
0 shrinks, and the respective flaps 8 and 25 rise from the topsheet 5 to block urine and other body fluids flowing on the topsheet 5 in the lateral direction, thereby preventing side leakage.
In addition, the pair of flaps 8 has a fold curve 21 and a side edge 1.
In addition to making the lines 5 and 16 parallel to the center line CC, an appropriate angle may be provided, for example, to draw a V-shape expanding from the crotch region 4 toward the front body 2 directions.

In the present invention, the flaps 8 and 25 are made of a liquid-permeable or liquid-impermeable, more preferably a gas-impermeable liquid-permeable, non-woven fabric that is comfortable to the touch. Also,
Non-woven fabric or perforated plastic film,
The back sheet 6 has a plastic film and an absorbent core 7
Crushed pulp or a mixture of crushed pulp and a superabsorbent polymer can be used. In addition, in order to join the flaps 8 and 25 to the topsheet 5, in addition to an adhesive or a pressure-sensitive adhesive including a hot-melt adhesive, if the sheet material is heat-meltable, a welding technique is used. Can be.

[0017]

In the diaper according to the present invention, the penis of the wearer is received between the left and right flaps, and the penis is held lightly by the bent edges of the flaps. , And it is possible to prevent side leakage.
